Energy Catalyzer

The Energy Catalyzer (also called E-Cat) is a purported cold fusion or Low-Energy Nuclear Reaction (LENR) heat source[1][2] which was devised by inventor Andrea Rossi[3][4] with support from physicist Sergio Focardi.[5][6] An Italian patent, which received a formal but not a technical examination, describes the apparatus as a "process and equipment to obtain exothermal reactions, in particular from nickel and hydrogen".[7][8] Rossi and Focardi said the device worked by infusing heated hydrogen into nickel powder, transmuting it into copper and producing heat.[9][10] The international patent application[1] received an unfavorable international preliminary report on patentability because it was adjudged to "offend against the generally accepted laws of physics and established theories".[11]

The device has been the subject of demonstrations and tests several times, and commented on by various academics and others, but no independent tests have been made, and no peer-reviewed tests have been published. Steve Featherstone wrote in Popular Science that by the summer of 2012 Rossi's "outlandish claims" for the E-Cat seemed "thoroughly debunked" and that Rossi "looked like a con man clinging to his story to the bitter end."[12]

Theoretical astrophysicist Ethan Siegel and nuclear physicist Peter Thieberger argue that the claims for the E-Cat are incompatible with the fundamentals of nuclear physics.[13][14] In particular, the Coulomb barrier for the claimed fusion reaction is so high that it is insurmountable anywhere in the known universe, including the interior of stars. The reaction also would create gamma radiation that would have penetrated the few inches of shielding apparently provided by the E-Cat, inducing acute radiation syndrome in persons in the vicinity of the purported demonstrations.[13] Given numerous other scientific inconsistencies – such as the ratio of isotopes in the supposed copper "fusion product" being identical to that in natural copper[15] – the authors argued that it is now time "for the E-Cat's proponents to provide the provable, testable, reproducible science that can answer these straightforward physics objections."[13]

Peter Ekström, lecturer at the Department of Nuclear Physics at Lund University in Sweden, concluded in May 2011, "I am convinced that the whole story is one big scam, and that it will be revealed in less than one year."[16] He cited the unlikelihood of a chemical reaction being strong enough to overcome the Coulomb barrier, the lack of gamma rays, the lack of explanation for the origin of the extra energy, the lack of the expected radioactivity after fusing a proton with 58Ni, the unexplained occurrence of 11% iron in the spent fuel, the 10% copper in the spent fuel strangely having the same isotopic ratios as natural copper, and the lack of any unstable copper isotope in the spent fuel as if the reactor only produced stable isotopes.[16] Kjell Aleklett, physics professor at Uppsala University, said the percentage of copper was too high for any known reaction of nickel, and the copper had the same isotopic ratio as natural copper. He also stated, "Known chemical reactions cannot explain the amount of energy measured. A nuclear reaction can explain the amount of energy, but the knowledge we have today says that this reaction cannot take place."[17]Scientific skepticJames Randi, discussing the E-Cat in the context of previous cold fusion claims, suggested that it will eventually be proven to be a fraud.[18]

Other reactions to the device have been mixed. In 2011 Dennis M. Bushnell, Chief Scientist at NASALangley Research Center, described LENR as a "promising" technology and praised the work of Rossi and Focardi.[19] Roland Pettersson, retired Associate Professor from the University of Uppsala, who witnessed a 2011 demonstration said "I'm convinced that this works, but there is still room for more measurements".[20]

Physicists Hanno Essén and Sven Kullander stated that if the claims that they had read about the E-Cat were true, then it must operate through some kind of a nuclear reaction. However, they had no access to privileged information about the catalysts in Rossi's device. According to Kullander it is "important to consider the experimental facts and not indulge too much in speculation about what could happen in theory". Kullander also emphasized that measurements of excess heat must be made accurately and independently: "You have to rely on Rossi that he is true to what he conveys and through discussions with him we may try to conclude how reliable the measurements are."[21][22]

Theoretical nuclear physicist Yeong E. Kim of Purdue University has proposed a potential theoretical explanation of the reported results of the device,[23] but has stated that, for confirmation of this theory, "it is very important to carry out Rossi-type experiments independently."[24] Kim had previously put forward this theory to explain the results of the discredited Fleischman and Pons cold fusion experiment in 1989.[25]

An application in 2008 to patent the device internationally had received an unfavorable preliminary report on patentability at the World Intellectual Property Organization[26] from the European Patent Office, noting that the description of the device was based on "general statements and speculations" and citing "numerous deficiencies in both the description and in the evidence provided to support its feasibility" as well as incompatibilities with "generally accepted laws of physics and established theories."[27] The patent application was published on 15 October 2009.[1]

In March 2014 the US Patent Office replied to Rossi's US patent application with a provisional decision to reject it, saying "The specification is objected to as inoperable. Specifically there is no evidence in the corpus of nuclear science to substantiate the claim that nickel will spontaneously ionize hydrogen gas and therefore 'absorb' the resulting proton".[30][31]

Invited guests attended several demonstrations in Bologna in 2011.[32][33][34] The device has not been independently verified. Of a January demonstration, Discovery Channel analyst Benjamin Radford wrote that "If this all sounds fishy to you, it should," and that "In many ways cold fusion is similar to perpetual motion machines. The principles defy the laws of physics, but that doesn't stop people from periodically claiming to have invented or discovered one."[35] According to PhysOrg (11 August 2011), the demonstrations held from January to April 2011 had several flaws that compromised their credibility and Rossi had refused to perform tests that could verify his claims.[2]

University of Bologna researchers have attended some E-Cat demonstrations, but only as observers. On 5 November 2011, the University of Bologna clarified that its researchers had not been involved in the demonstrations and that none of those took place at the university. Rossi had signed a contract with the university, but the contract was terminated and no research was done because Rossi did not make the first payment.[36][37][38][39][40]

Skeptic Ian Bryce believes that the E-Cat was misconnected during demonstrations, and that the power attributed to fusion is supplied to the device through the earth wire.[41][42]Dick Smith offered Rossi one million dollars to demonstrate that the E-Cat system worked as claimed, while the power through the earth wire was also being measured, which Rossi refused.[43][44] Peter Thieberger, a senior physicist at Brookhaven National Laboratory, said it would be very difficult for this misconnection to happen by accident and that the issue could only be cleared with a fully independent test.[41]

Another demonstration on 6 October 2011 reportedly lasted for about eight hours.[45][46] Roland Pettersson, retired Associate Professor from the University of Uppsala, who witnessed it said "I'm convinced that this works, but there is still room for more measurements".[20]

On 28 October 2011 the unit was "customer tested" and was said to release 2,635 kWh during five and a half hours of self-sustained mode, an average power of 479 kilowatts – just under half the promised power of one megawatt. Independent observers were not allowed to watch the measurements or make their own, and the plant remained connected to a power supply during the test allegedly to supply power to the fans and the water pumps.[47][48][49][50]

Because of his research into cold fusion for over 15 years, Sergio Focardi was contacted by Andrea Rossi in 2007 in order to validate the apparatus at its early stage of development.[51][52] After four years of work and measurements together with Rossi, Focardi concluded that nuclear fusion reactions happen inside the Energy Catalyzer. Focardi states that the nuclear process is facilitated by a secret additive, known only by Rossi and not by him. According to Focardi, the process would be much less intense without this additive.[32] Rossi and Focardi are then reported to have been unable to find a peer-reviewed scientific journal that would publish their paper describing how they claim the Energy Catalyzer operates.[53] Their paper appears only in Rossi's self-published blog,[54]Journal of Nuclear Physics.[55]

In May 2013 a non-peer-reviewed paper describing "results obtained from evaluations of the operation of the E-Cat HT in two test runs" was submitted to the arXiv digital archive.[56] Although the authors of the paper wrote that they were not in control of all of the aspects of the process, they concluded that, even by the most conservative of measurements, the device produced excess heat with a resulting energy density that was at least one order of magnitude, and possibly several, higher than any other conventional energy source, including gasoline.[57][58][59] The test was partly funded by the Swedish energy research consortium, Elforsk.[60] Elforsk stated on their website that the results were very remarkable, but that it was highly questionable to speculate whether nuclear transformation had occurred when no access had been provided to the reactants.[61] In a response to the original manuscript archived on arXiv, commentators criticized the testing as not truly independent, described the report as having "characteristics more typically found in pseudo‐scientific texts", and stated that "The authors seem to jump to conclusions fitting pre‐conceived ideas where alternative explanations are possible."[62][63][64] Astrophysicist Ethan Siegel commented at ScienceBlogs saying Rossi did not allow the reactants or products to be measured on this occasion. In the previous tests there were not enough 62Ni and 64Ni (the only two nickel isotopes which can fuse with hydrogen), at 3.6% and 0.9% respectively, in the reactants to explain the 10% copper output; these isotope levels are typical of natural copper, rather than of fusion by-product. According to Siegel, Rossi also refused to unplug the machine while it was operating despite it being an easy way to surreptitiously power the device. He also added that the supposedly independent testers had to rely on data supplied by Rossi.[65]

In October 2014 a non-peer-reviewed paper by the same authors as the May 2013 report describes results from evaluations in March 2014 of an upgraded version of the E-Cat which runs at higher temperatures. Unlike previous demonstrations, the test was carried out with monitoring equipment and in a laboratory not supplied by Rossi, and was run over an extended duration (32 days).[66] However, as with the previous report, the authors were not in full control of the process; Rossi intervened during the insertion of the fuel charge, start up of the reactor, shut down of the reactor, and extraction of the spent fuel. Overall, the total excess heat measured was calculated to be well beyond that possible by any conventional, non-nuclear source. In this report, they present analyses of samples of spent fuel, concluding from the isotopes found that "nuclear reactions are therefore indicated to be present in the run process, which however is hard to reconcile with the fact that no radioactivity was detected outside the reactor during the run." Following fuel and ash isotopic analysis, the authors speculate that isotopes of especially nickel and lithium being part of the reaction, in particular transmutation of 58Ni and 60Ni to 62Ni, and from 7Li to 6Li through some unknown process.

Particle physicist Tommaso Dorigo commented on the 2014 test, called the isotopic measurements “startling” but he expressed deep concern about Rossi being involved in collecting the spent fuel, that the testers may have “overlooked some simple trick” and that “given the extraordinary nature of the claim… this constitutes a major flaw, which totally invalidates any conclusions one might otherwise draw.”[67] Astrophysicist Ethan Siegal was highly critical of the test, stating that the testers were not independent, Rossi could have tampered with the fuel samples, that the 'open calorimeter' set up used was inappropriate, and that “it’s relatively easy to fake the amount of energy being drawn through a power cord if there is a hookup to an external source.”[68]

At 4 minutes and 34 seconds, Bushnell described several emerging energy technologies, but he identified LENR as "the most interesting and promising at this point". At 10 minutes and 35 seconds, Bushnell continued: "... in January of this year Rossi, backed by Focardi, who had been working on this for many years, and in fact doing some of the best work worldwide, came out and did a demonstration first in January, they re-did it in February, they re-did it in March, where for days they had one of these cells, a small cell, producing in the 10 to 15 kilowatts range, which is far more than enough heat to boil water for tea."
